Prefer HTTPS to FTP and HTTP in documentation 2017-09-13T22:54:37+00:00 Paul Eggert 2017-09-13T22:52:52+00:00 bc511a64f6da9ab51acc7c8865e80c4a4cb655c2 Most of this change is to boilerplate commentary such as license URLs. This change was prompted by ftp://ftp.gnu.org's going-away party, planned for November. Change these FTP URLs to https://ftp.gnu.org instead. Make similar changes for URLs to other organizations moving away from FTP. Also, change HTTP to HTTPS for URLs to gnu.org and fsf.org when this works, as this will further help defend against man-in-the-middle attacks (for this part I omitted the MS-DOS and MS-Windows sources and the test tarballs to keep the workload down). HTTPS is not fully working to lists.gnu.org so I left those URLs alone for now.

Improve --enable-gcc-warnings for MinGW64 2017-09-09T18:11:51+00:00 Paul Eggert 2017-09-09T18:10:35+00:00 d63123542ffd60dbec0c9038144329b99f0f1d65 This partially reverts my 2016-05-30 patch.

(internal_lisp_condition_case): Use it. * src/tparam.c (tparam1): Use FALLTHROUGH to pacify GCC.

Add support for arguments in emacsclient's ALTERNATE_EDITOR (Bug #25082) 2017-08-30T20:59:38+00:00 Reuben Thomas 2016-12-01T15:21:57+00:00 98f01a13a3bf2a4db2dcc82a342ee017326de732 * lib-src/emacsclient.c (fail): Parse ALTERNATE_EDITOR, or corresponding command-line argument, into quote- or space-separated tokens. If a token starts with a quote, then it naturally is expected to end with a quote; escaping is not supported. This is enough to cope with the typical case of requiring the initial path to be quoted, common on Windows where it may contain spaces. * etc/NEWS: Document. * doc/emacs/misc.texi: Likewise. * doc/man/emacsclient.1: Tweak to remove the implication that only an editor can be specified (the manual already mentions a “command”). Fix a small error where “EDITOR” is referred to rather than “ALTERNATE_EDITOR”. * test/lib-src/emacsclient-tests.el: Add tests.
